Hi

Have been running Ubuntu Mate 17.10 for several months without issue. Just upgraded to 18.04LTS and now my monitor resolution is all wrong and under System > Preferences > Hardware> Display preferences my monitor is unknown.

The results of the following command lspci -nnk | grep -i vga -A3

Quote:

43:00.0 VGA compatible controller [0300]: NVIDIA Corporation GV100 [10de:1d81] (rev a1)
Subsystem: NVIDIA Corporation GV100 [TITAN V] [10de:1218]
Kernel driver in use: nvidia
Kernel modules: nvidiafb, nouveau, nvidia_390, nvidia_390_drm

How can I resolve this issue?

Are there no options for monitor refresh and screen resolution? Is this connected to a laptop external port? What kind of port is it? HDMI can be flakey. But you can use xrandr to manually set a resolution for the respective video output.

that's weird. androids that are linux based that are on store shelves never have that issue

You might want to blacklist the nouveau driver.
